CC -!- FUNCTION: Catalyzes the last two sequential reactions in the de novo
CC biosynthetic pathway for UDP-N-acetylglucosamine (UDP-GlcNAc). The C-
CC terminal domain catalyzes the transfer of acetyl group from acetyl
CC coenzyme A to glucosamine-1-phosphate (GlcN-1-P) to produce N-
CC acetylglucosamine-1-phosphate (GlcNAc-1-P), which is converted into
CC UDP-GlcNAc by the transfer of uridine 5-monophosphate (from uridine 5-
CC triphosphate), a reaction catalyzed by the N-terminal domain.
CC {ECO:0000255|HAMAP-Rule:MF_01631}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=acetyl-CoA + alpha-D-glucosamine 1-phosphate = CoA + H(+) + N-
CC acetyl-alpha-D-glucosamine 1-phosphate; Xref=Rhea:RHEA:13725,

CC Evidence={ECO:0000255|HAMAP-Rule:MF_01631};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + N-acetyl-alpha-D-glucosamine 1-phosphate + UTP =
CC diphosphate + UDP-N-acetyl-alpha-D-glucosamine; Xref=Rhea:RHEA:13509,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:33019, ChEBI:CHEBI:46398,

CC -!- PATHWAY: Nucleotide-sugar biosynthesis; UDP-N-acetyl-alpha-D-
CC glucosamine biosynthesis; N-acetyl-alpha-D-glucosamine 1-phosphate from
CC alpha-D-glucosamine 6-phosphate (route II): step 2/2.
CC {ECO:0000255|HAMAP-Rule:MF_01631}.
CC -!- PATHWAY: Nucleotide-sugar biosynthesis; UDP-N-acetyl-alpha-D-
CC glucosamine biosynthesis; UDP-N-acetyl-alpha-D-glucosamine from N-
CC acetyl-alpha-D-glucosamine 1-phosphate: step 1/1. {ECO:0000255|HAMAP-
